f. A study of the physical characteristic of honey was conducted due to the large demand of royal jelly. A capillary tube viscometer was used by a researcher in determining the viscosity of the honey. The viscometer is 250 mm long with an outside diameter of 55mm and effective thickness of 2.5mm and was used horizontally so that the effect of gravity was neglected. At an ambient temperature of 30°C the following data were collected: Q (cc/s) 1.25 1.55 1.80 2.05 ДР (Ра) 10.0 12.5 15 17.5 20.0 2.55 What will be the stress produced per unit length in the tube used in the production of royal jelly if it has a radius of 5mm and a flow of 1 capsule per second. (1 capsule = 0.85 cc of royal jelly).

A journal bearing of 50 mm diameter supports a shaft running at a speed of 320 rpm. A lubricating oil of absolute viscosity of 0.06 kg/m-s is used. The oil is found to operate satisfactorily with a diametral bearing clearance of 0.15 mm and a bearing pressure of 1.5 N/mm. Consider Sommerfeld number as 14.3 x 10°, a constant. (i) If it is necessary to change the speed to 400 r.p.m, determine the pressure at which the bearing should operate. If, when designed for a speed of 320 r.p.m, and pressure of 1.5 N/mm, the clearance had been made 0.12 mm, what change should be made in (ii) the oil?

A 1.5-inch diameter pipe extends vertically from the bottom of the tank and is 5 m long. The oil level in the tank remains constant at 3 m above the bottom of the tank. In a case with friction the discharge speed can be obtained in the form of the following Equation. Calculate the flow rate of oil discharged per hour. Assume that the pipe is commercial steel (ε=0.05 mm). V= 2gh +f-
